72xy^(3)
4-3 = 1
- - x + 3 = x + 3
3x+3-2x=3 x+3=3 x-0
(3+2i)-(3+2i)

1 over a^5b^3
The expression cannot be simplified.
33z - 4 - 20z - 5 simplified would be 13z - 1.
A numerical expression is ' 2 + 3' A numerical equation is ' 2 + 3 = 5'.
The expression 5a - 2/3 is a combination of a term involving the variable 'a' and a fraction. To simplify this expression, you would first distribute the 5 to the 'a' term, resulting in 5a. Then, you would subtract 2/3 from 5a. The expression cannot be further simplified without knowing the specific value of 'a'.
